BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an implement, such as header for acombine, that includes an integral transport system to enable theimplement to be pulled lengthwise for transport of the implement, and inparticular to an implement in which the transport system components arecarried onboard the implement when the implement is used in the field.

2. Description of Related Art

To increase harvesting efficiency, harvesters, such as combines, haveincreased in size and capacity over the years. With this increase incapacity, the detachable header used for picking the crop has increasedin width as well. A wider header increases efficiency by reducing thenumber of passes through the field required by the harvester to coverthe entire field. However, the increased width of the header hasresulted in transportation difficulties in moving the combine and headerfrom field to field. With a wide header on a combine, it can bedifficult to drive the combine on roads, and difficult or evenimpossible to cross narrow bridges. Vehicle width limitations on publicroads may preclude transporting wide headers on the front of a combine.

One solution for the transport problems created by a wide header is toplace the header on a trailer and pull the header in a lengthwisedirection. This solution has the disadvantage of the added cost andupkeep of the trailer. Another problem is that harvesting may begin atone location in the field with the trailer left there, while theharvesting is completed at another location, or even another fieldseveral miles from the trailer.

Another solution for the transport problems created by a wider header isto equip the header with towing equipment, such as wheels and a tongue,enabling the header to be pulled lengthwise on its own wheels fortransport. This eliminates the need for a separate trailer. Many suchheaders have components that are removed from the header and left in thefield when harvesting begins. As with a trailer, these components may beseveral miles away from the combine when they are again needed. Someheaders have been equipped with onboard towing equipment, but it isoften difficult to change the header between the transport andharvesting configurations. Other headers fold, either upward or forward,to reduce the header width for transport.

SUMMARY OF THE INVENTION

It is an object of the present invention to provide an integraltransport system for a combine header in which all components of thetransport system are carried onboard the header when the header isconfigured for harvesting.

It is a feature of the present invention that the header can bereconfigured from harvesting to transport and vice versa quickly andeasily, without the use of hand tools.

It is a further feature of the present invention that the two wheelsused for towing the header can also be utilized as gauge wheels for theheader during harvesting.

The integral transport system of the present invention provides oneground-engaging wheel for towing the header on the rear side of theheader coupled to the header frame. A second ground-engaging wheel ismounted to a swing arm that extends downwardly and forwardly from theframe, on the front side of the header beneath the cutterbar. A braceextends downwardly from the frame immediately beneath the cutterbar tohold the swing arm in the transport position. The brace is removablyattached to the frame front cross member at the cutterbar. The brace isreleased from the frame front cross member to enable the swing arm to berotated to the rear of the header in a stowed position for harvesting.The brace is then attached to the rear of the header frame to hold theswing arm up against the bottom of the header.

For those headers wide enough to require gauge wheels, the two groundengaging wheels are mounted to the header and aligned in the combinetravel direction to function as gauge wheels. For those headers that arenot equipped with gauge wheels, mounting brackets are provided on therear of the header to carry the wheels during harvesting.

A trailer tongue is retractably stored along the bottom of the header.The tongue can be extended from one end of the header and locked inplace by pins for transport. A tongue jack is removably attached to thetongue to support the extended tongue above the ground. The jack isremoved from the tongue for harvesting and mounted to a bracket on therear of the header.

The end of the header opposite from the trailer tongue is equipped witha pair of light bars. The light bars have a stowed position within anend sheet cover, where the lights are protected from damage duringharvesting. The end sheet cover is removed to access the light bars andto move the light bars to transport positions in which they extend fromthe header to indicate the full width of the header during transport. Inaddition, a slow moving vehicle sign is rotated from a stowed positionbeneath the end sheet cover to a visible transport position. The endsheet cover is then reinstalled for transport.

All of the moving components of the transport system are locked in placeby retaining pins, enabling the header to be converted between transportand harvesting configurations without the need for hand tools tomanipulate fasteners.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIG. 1, a header for a combine having the integraltransport system of the present invention is shown and designatedgenerally at 10. The header 10 includes a main frame 12 that extendslaterally between opposite ends 14 and 16. The main frame 12 includes anupper beam 18 that extends between the opposite ends 14 and 16, aplurality of support arms 19, 20, 21, 22, 23, 24 that extend downwardand forward from the upper beam, and a front cross member 25 (FIG. 4)welded to the support arms at a front edge of the header. The header 10includes a rear wall 26 and a cutterbar 28 is disposed along the frontcross member 25 for cutting a standing crop. A reel, not shown, issupported on a pair of reel support arms 30 at the two ends 14, 16 in aconventional manner.

The interior support arms 20, 21, 22, 23 of the main frame include anupright rear portion 32 behind the rear wall 26 and a bottom portion 34extending forward from the lower end of the upright rear portion 32 tothe front cross member 25. The rear wall 26 includes an opening 36 forreceiving cut crop material to move this material rearwardly into thefeederhouse of a conventional combine (not shown).

An attachment frame 38 is used to mount the header to a combinefeederhouse. The attachment frame 38 includes forward extending leafsprings 40, only one of which is shown, that are attached to the bottomportion of two of the support arms 21, 22, to provide a suspensionbetween the main frame 12 and the attachment frame 38. A tumbuckle 42couples the upper beam 18 of the main frame to the attachment frame 38.The attachment frame 38 is rigidly coupled to the combine feederhouse ina conventional manner.

Because of the width of the header 10, the header is provided with atransport system to enable the header 10 to be towed in a lengthwisedirection. The transport system includes a pair of ground engaging tireand wheel assemblies, each including an inflatable tire 56 and a metalwheel 58 (FIG. 2). The tire and wheel assemblies will be referred toherein as “wheels” and it will be understood that the term “wheel”refers to both the inflatable tire and the metal wheel. One groundengaging wheel 50 is mounted along the rear side of the header whileanother ground engaging wheel 52 is mounted along the front edge of theheader. The wheels 50, 52 support the header both fore and aft of theheader center of gravity. A retractable trailer tongue 54 is provided atone end of the header for attaching the header to a towing vehicle.Depending on the width of the header, the ground engaging wheels 50 and52 may also be used as gauge wheels, as shown in phantom line, on eachside of the header during harvesting.

With reference to FIGS. 2, 3 and 4, the mounting of the front wheel 52in the transport position is shown. The wheel 52 is mounted to a hub 64.The hub 64 is rotatably carried on a spindle 66 by a bearing assembly(not shown) in a conventional manner for mounting a rotating wheel. Thespindle 66 is inserted into a spindle receiver 70, in the form of ahollow tube. The spindle receiver 70 is rotatably mounted inside asleeve 72. The spindle receiver 70 is retained in the sleeve 72 by atransverse pin 74 passing through the spindle receiver 70 at one end ofthe sleeve and a transverse tube 78 (FIG. 5) welded to the spindlereceiver 70 at the opposite end of the sleeve 72. The tube 78 and pin 74capture the spindle receiver 70 within the sleeve 72.

In the transport position shown in FIG. 3, a pin 80 passes through thesleeve 72, the spindle receiver 70 and the spindle 66. The pin 80 thusretains the spindle 66 within the spindle receiver 70 and also preventsrotation of the spindle and spindle receiver within the sleeve 72.

The sleeve 72 is welded to the end of a swing arm 84. The swing arm 84is coupled to the bottom portion 34 of the support arm 22. The swing armis mounted on a pivot pin 86, held in place by a retaining pin 88. Theswing arm 84 is rotatable about the axis 90 of the pivot pin 86. Theaxis 90 extends transverse to the direction of header travel duringharvesting.

In the transport position, the swing arm 84 extends downwardly andforward from the pivot pin 86. The swing arm is maintained in thisposition by a brace 94. The brace 94 is removably attached to the frontcross member 25 by a pair of mounting pins 96 biased by springs 98. Thepins 96 extend through apertures in flanges 100 welded to the frontcross member 25. The mounting pins 96 can be retained in positionswithdrawn from the flanges 100 by cross pins 102 that retain the springs98. These cross pins are seated against blocks 104 cast into the end ofthe brace 94 to hold the mounting pins 96 in retracted positions asshown in FIG. 5. This facilitates movement of the brace between thestowed and transport positions, allowing the brace to be placed inposition without the need to manually hold the mounting pins 96 inretracted positions. The lower end 106 of the brace is forked, havingtwo flanges 108 that are placed on opposite sides of the swing arm 84 asshown in FIG. 3. The lower end 106 of the brace 94 is coupled to theswing arm 84 by a pin 110, extending through both the brace flanges 108and the swing arm 84. In the transport position with the brace 94coupled to the front cross member 25 and the swing arm 84, the brace 94supports the swing arm 84 and prevents rotation of a swing arm about thepivot pin 86.

In the preferred embodiment, the swing arm 84 is a weldment constructedof tube sections welded together at the joint 112. The brace 94 is aniron casting. Secondary flanges 114 extend from the end 106 of the brace94 and are positioned on opposite ends of the tube 78 that is welded tothe spindle receiver 70. A pivot bolt 116 extends through the flanges114 and the tube 78 and is retained by a nut 118.

The header is converted from transport to harvesting configurations byfirst raising the header and removing the wheel 52. The wheel 52 isremoved by withdrawing the pin 80, enabling the spindle 66 to bewithdrawn from the spindle receiver 70. With the wheel 52 removed, theupper end of the brace 94 is uncoupled from the front cross member 25.This enables the swing arm 84 to rotate about the pivot pin 86 downwardand rearward such that it extends rearward from the pin 86 along thebottom portion 34 of the support arm 20. The pin 110 that couples thebrace end 106 to the swing arm is removed from the brace 94 and swingarm 84. The brace 94 is rotated about the pivot bolt 116 in the tube 78to withdraw the flanges 108 from the opposite sides of the swing arm 84.Once the flanges 108 have cleared the swing arm, the brace 94 and thespindle receiver 70 are rotated about the axis 122 of the sleeve 72 asshown by the arrow 120 in FIG. 5. An intermediate position of the brace94 is shown in FIG. 5, after approximately 90° of rotation of the braceand spindle receiver about the sleeve axis 122.

FIG. 6 illustrates the swing arm 84 and brace 94 in stowed positions forharvesting. The upper end of the brace 94 is secured to mounting flanges124 projecting from the upper beam 18 in the same manner in which thebrace is secured to the front cross member 25 in the transport position.Retention of the brace 94 to the upper beam 18 secures the swing arm 84in its stowed position in which it extends rearward, adjacent to thebottom portion 34 of the support arm 22. The pin 110 is inserted in theswing arm 84 and held in place by the retaining pin 126 to store the pin110 during harvesting of the header. The swing arm 84, in the stowedposition does, not extend downward from the header frame, but ispositioned alongside the bottom portion of the support arm 22. Thus, theswing arm 84 does not affect the ground clearance of the header 10. Asshown and described, the swing arm is also moved between the stowed andtransport positions by manipulation of pins, without the need for handtools.

The rear wheel 50 is mounted to a wheel hub 64 and spindle 66 asdescribed above in connection with the wheel 52. The wheel 50 is mountedto a spindle receiver 115 (FIG. 2) fixed to the upright member 128 ofthe attachment frame 38. The wheel 50 is retained in the spindlereceiver 115 by a pin in the same manner at the wheel 52. The locationof the spindle receiver 115 on the attachment frame and its orientationis such that it is substantially aligned with the axis of the spindlereceiver 70 along the front edge of the header for the wheel 52. Thewheels 50, 52 are thus closely aligned with one another.

When the wheels 50 and 52 are removed from their transport positions,they are mounted to the upper beam 18 in a storage position (not shown)or used as gauge wheels as follows. For use as gauge wheels, the wheels50, 52 are pivot carried by the support arms 20 and 23 to support theends of the header during harvesting. With reference to FIG. 7, thecoupling of the wheel 52 to the support arm 20 in a gauge wheel positionis shown. An arm 130 extends rearward from the bottom portion of thesupport arm 20. The rearward end of the arm 130 supports a spindlereceiver 132 like the spindle receiver 70 and receives the spindle 66 tomount the wheel 52. The arm 130 is rotatably mounted to the support arm20 and is supported by an inflatable airbag suspension member 134,positioned between the arm 130 and a support bracket 136 fixed to thesupport arm 20. The airbag 134 provides an air-cushioned suspension tothe gauge wheel 52. Another gauge wheel mounting structure is providedon the support arm 23 to support the other wheel 50 in a gauge wheelposition for harvesting.

Whether the wheels 50, 52 are carried on the upper beam 18 or used asgauge wheels during harvesting, the wheels remain with the header, andare thereby available when the harvesting is completed and it is againnecessary to transport the header 10.

The header also includes a retractable trailer tongue 54 for towing theheader in a lengthwise direction. The tongue 54 is carried by the mainframe for movement between a retracted, stowed position shown in FIG. 8,and an extended transport position shown in FIGS. 1 and 9. As seen inFIG. 1, the tongue extends from the end 16 of the header. The tongue 54is a tubular member and is movable in a cradle 140. The cradle is formedof a pair of identically shaped triangular plates 142 spaced apart bypins 144 at the two upper corners of the plates 142 and by a pivot pin146 at the lower corner of the plates 142. The tongue 54 slides in thecradle 140 between the pivot pin 146 and the two upper pins 144.

The cradle 140 is in turn mounted to a pivot arm 150 formed by spacedplates 152 positioned outside the plates 142 of the cradle 140. Thepivot arm 150 is pivotally mounted to the support arm 19 by a pin 154shown in FIG. 9. The pivot arm 150 has a pair of apertures, a loweraperture 156 shown in FIG. 8 and an upper aperture 158 shown in FIG. 9.In the retracted, stowed position of the tongue, a pin 162 extendsthrough the upper aperture 158 in the pivot arm and through the aperture164 in the tongue, near the distal end of the tongue, to secure thetongue to the pivot arm 150.

The tongue 54 has an abutment plate 166 that extends downward below thelower surface of the tongue. When the tongue is slid to the retracted,stowed position, the plate 166 engages the pin 146, causing the pivotarm 150 to rotate inwardly and upwardly to raise the tongue 54. When theaperture 158 in the pivot arm and the aperture 164 in the tongue arealigned, the pin 162 is inserted therethrough to retain the tongue 54 inthe retracted, stowed position. In this raised position, the tongue 54is held against the bottom portions 34 of the support arms 19, 20.

The tongue 54 is shown in an extended towing position in FIG. 9. In thisposition, the pivot arm 150 is lowered and the pin 162 is insertedthrough the lower aperture 156 in the pivot arm, through the centeraperture 170 in the cradle 140 and through an aperture in the tongue 54.This locks the pivot arm, cradle and tongue together. In the extendedposition, the end 172 of the tongue 54 is adjacent the bottom portion 34of the support arm 20 as best illustrated in FIG. 10. Further extensionof a tongue 54 is prevented by a cross pin 174 carried by the tongue.The cross pin 174 seats in “V” shaped plates 176 extending transverselyfrom the bottom portion 34 of the support arm 20. A spring biasedlocking pin 180 is movable across the end 172 of the tongue and retainedin plates 182 on each side of the tongue. This prevents the tongue frommoving inward, toward the retracted position during transport of theheader. The locking pin 180 is biased by a spring 184 into the lockedposition in the two plates 182. A hook retaining plate 186 is providedon the support arm 20 to hold the pin 180 in an open position when thetongue 54 is moved inward to its retracted, stowed position.

Pins 192, 194 (FIG. 9) removably mount a tongue jack 190 to the tongue54. The pins 192, 194 are inserted through the apertures 196, 198 (FIG.8) in the tongue respectively. The pins 192 and 194 are of differentdiameter as are the apertures 196, 198 to ensure that the jack stand 190is mounted on the proper side of the tongue 54. When the header 10 isharvesting, the jack stand 190 is mounted to a bracket 200 (FIG. 9)welded to the upper beam 18. The bracket 200 has a pair of apertures,identical to the apertures 196, 198 in the tongue, for mounting the jack190 thereto. By storing the tongue 54 and jack 190 on board the headerduring harvesting, these components will remain with the header and beavailable when the header is once again converted to the transportconfiguration.

With reference once again to FIG. 1, the header 10 is shown with lightsmounted to the header end 14, opposite the tongue 54. Light bars 210 and212 extend fore and aft from the header. Each light bar carries one ormore lights, such as lights 214 and 216. The lights define the width ofthe header, as it is pulled lengthwise. The light bars 210 and 212 aremovable from the extended position shown in FIG. 1, to stowed positionsbeneath the cover 218 of the header end sheet. To move the light bars totheir stowed positions, the cover 218 is first removed. The light bar210 is carried on a post 222 and has a tube 224 surrounding the post222. A spring locking pin 226 holds the bar 210 in a fixed position onthe post 222. With the cover 218 removed, and the spring locking pin 226removed, the light bar 210 is moved outward toward the end of the post222 and rotated approximately 180° to the stowed position resting on astop 228. The spring locking pin 226 is again inserted through the post222 and the tube 224 of the light bar to retain the light bar 210 in thestowed position.

The light bar 212 is similarly mounted to a post 230. The light bar 212is removed from the post 230 and remounted to a second post 232 suchthat the bar 212 is stowed adjacent to the light bar 210 and on a stop238. The light bar 212 is retained in place on the posts by a springlocking pin 240. The slow moving vehicle sign 234 is also rotateddownward over the two light bars 210, 212 without the use of hand tools.The cover 218 is then returned to a position covering the light bars andthe slow moving vehicle sign during harvesting. The cover 218 protectsthe lights from damage during harvesting. The light bars areelectrically connected through a wiring harness 236 that extends thelength of the header 10 and is coupled to a towing vehicle to provideelectrical power to the lights in a known manner.

The components of the transport system of the present invention arecompletely stored on board the header when the header is harvesting. Theheader can be converted between transport and harvesting configurationswithout the use of hand tools. The swing arm 84 and brace 94 are theonly wheel supporting members that need to be moved between transportand harvest positions, resulting in a header that has a minimal numberof components to be moved and reconfigured between transport andharvesting configurations.

The transport system of the present invention has been described andshown in the context of a header for a combine. The transport systemcan, however, be used in other implements that have a great width duringfield use. Planters and tillage implements are two examples of wideimplements for which special provisions are needed for transport of theimplement on a road. The integral transport system of the presentinvention can be integrated into these, and other implements, withoutdeparting from the scope of the present invention.
